Are you a fan of alliums, too? You're in the right place then! Allium (ornamental onion) is a flower bulb of which there are about 700 varieties. Each one seems more beautifully coloured or to have an even more special shape than the last. The ornamental onion is perfect for making all kinds of plant combinations, both in the garden and in a flower box. The flower bulb is perfect in combination with other Garden Plants and Flower Bulbs. In addition, the allium is also very easy to care for. It loves a sunny spot, but even in a shadier garden these fascinating flowers are real eye-catchers. And they come back the year after that!
Late spring bloomers
Most varieties of ornamental onions bloom in June, shortly after the real spring bloomers and just before most summer bloomers. These flower bulbs are therefore must-haves for your garden's transition from spring to summer. Allium bulbs must be planted in autumn. That's why alliums are categorised as spring flowering bulbs. You have to wait a bit, but in May your patience will be rewarded! All the flowers of ornamental onions can also be used as cut flowers or dried flowers. The flowers last fairly long time; an average of 2 weeks in a vase.
Alliums can also stay in the same place in the garden for years. Immediately after flowering, give the bulbs organic fertiliser and allow the flowers and leaves to die completely. Trim off the dead foliage and the flowers will appear again the next spring. An ornamental onion in a flower pot is usually not frost-resistant, so store it in a frost-free place, for example in a shed.
